Since I'm not whitelisted, and you guys don't "know" me, my skills are largely a moot points, but I will share anyways.
I've been an Admin twice, once on a server where I was the Maze Admin (mazes were used as a whitelisting mechanism) and banned trolls, etc. I created mazes, changed maze orders, and generally liked making whities' lives miserable. You know the saying, "The only good whitie is a dead whitie".
On the second server I taught myself console commands so I could help on the backend. I also used WE, to create multiple features in the world.
